Dr. Timaran earned his medical degree at the University of Cauca Faculty of Health Sciences in Colombia in 1991. He completed surgical residencies at the National University of Colombia and the University of Tennessee Medical Center, followed by a fellowship in vascular surgery at Montefiore Medical Center/Albert Einstein College of Medicine. He joined UT Southwestern in 2004, and he earned a master’s degree in clinical sciences with distinction from UT Southwestern in 2008.

He has authored more than 80 peer-reviewed abstracts and more than 65 articles in peer-reviewed journals and has given more than 200 lectures and presentations around the world.

Dr. Timaran is a member of the American College of Surgeons, the American Medical Association, and the Society for Vascular Surgery. He holds the G. Patrick Clagett Professorship in Vascular Surgery.

Dr. Timaran is an expert in repairing complex abdominal aneurysms; he is one of only a few surgeons in the United States who performs aneurysm repair using fenestrated endovascular grafts, which are custom-made to each patient’s unique anatomy. This technique has enabled Dr. Timaran to treat people who are unfit for traditional open surgery and who previously would not have been considered candidates for minimally invasive techniques.

He also specializes in the endovascular repair of complex aortic and peripheral arterial problems, and he is UT Southwestern’s principal investigator for the National Institutes of Health-funded Carotid Revascularization Endarterectomy vs. Stenting Trial (CREST2), a multicenter study of the outcomes between traditional surgery and interventional techniques in the treatment of carotid disease, one of the main causes of stroke.

Because his training and expertise allows him to choose from and perform both open and endovascular procedures, no matter what issue he sees a patient for, his goal is to find the right approach for each person.

“We do what’s right for the patient,” he says.
